Inkcazelo yobuxoki:

1

I-phenomenon yokumisela ubuxoki kuthetha ukuba ngexesha lenkqubo yokuxuba ikhonkrithi, ikhonkrithi ilahlekelwa yi-fluidity ngexesha elifutshane kwaye ibonakala ingena kwisimo sokumisela, kodwa ngokwenene ukusabela kwe-hydration akwenzeki ngokwenene kwaye amandla ekhonkrithi akayi kuba. iphuculwe. Ukubonakaliswa okuthe ngqo kukuba umxube wekhonkrithi ulahlekelwa ngokukhawuleza iimpawu zayo zokuqengqeleka ngaphakathi kwemizuzu embalwa kwaye uba nzima. Iphantse iphulukane nolwelo lonke kwisiqingatha seyure. Emva kokuba ibunjwe ngokulambayo, inani elikhulu lemingxuma yobusi iya kufumaneka kumphezulu. Nangona kunjalo, le meko yoxinaniso yeyomzuzwana, kwaye ikhonkrithi isenako ukuphinda ifumane ulwelo oluthile xa ixutywe ngokutsha.

Uhlalutyo lwezizathu zokuxinana kobuxoki:

Ukwenzeka kwe-coagulation yobuxoki kubangelwa ikakhulu kwimiba emininzi. Okokuqala, xa umxholo wamacandelo athile kwi-samente, ngokukodwa i-aluminates okanye i-sulfates, iphezulu kakhulu, la macandelo aya kusabela ngokukhawuleza ngamanzi, okwenza ukuba ikhonkrithi ilahlekelwe yi-fluidity ngexesha elifutshane. Okwesibini, ukucoleka kwesamente kukwayinto ebalulekileyo echaphazela ukusetwa kobuxoki. Iincinci zesamente ezintle kakhulu ziya kwandisa indawo ethile kunye nokwandisa indawo ekudibaneni namanzi, ngaloo ndlela ikhawuleza isantya sokuphendula kwaye ibangele ukusetwa kobuxoki. Ukongeza, ukusetyenziswa okungafanelekanga kwee-admixtures kukwangunobangela oqhelekileyo. Umzekelo, imixube yokunciphisa amanzi isabela ngokwemichiza kunye namalungu athile kwisamente ukwenza izinto ezinganyibilikiyo. Ezi zinto zinganyibilikiyo ziyakufunxa isixa esikhulu samanzi, nto leyo ekhokelela ekuncitshisweni kolwelo lwekhonkrithi. Iimeko ezifana nobushushu kunye nokufuma kwindawo yokwakha kunokuchaphazela ukumanzi kwekhonkrithi, kubangele ukusetwa kobuxoki.

 

Isisombululo kwingxaki ye-coagulation yobuxoki ngolu hlobo lulandelayo:

Okokuqala, sebenza nzima ekukhethweni kwesamente. Iindidi zesamente ezahlukeneyo zinemichiza eyahlukeneyo kunye neempawu ezisebenzayo, ngoko ke kubalulekile ukukhetha iintlobo zesamente ezinokuthi zibangele ukusekwa kobuxoki. Ngokuhlola ngokucokisekileyo kunye nokuvavanya, sinokufumana i-samente efanelekileyo kakhulu kwiimfuno zeprojekthi yangoku, ngaloo ndlela sinciphisa kakhulu umngcipheko wokumisela ubuxoki.

Okwesibini, kufuneka silumke kakhulu xa sisebenzisa imixube. I-admixtures efanelekileyo inokuphucula ngokufanelekileyo ukusebenza kwekhonkrithi, kodwa ukuba isetyenziswe ngokungafanelekanga okanye ukuba i-admixtures engahambelani ne-samente ikhethiweyo, iingxaki zokubeka ubuxoki zingenzeka. Ngoko ke, kufuneka silungelelanise ngokufanelekileyo uhlobo kunye ne-dosage ye-admixtures ngokwemiqathango ethile yeprojekthi kunye neempawu zesamente, okanye ukwandisa ukusebenza kwazo ngokudibanisa ukuqinisekisa ukuba ikhonkrithi inokugcina i-fluidity enhle.

Ekugqibeleni, ubushushu bommandla wokwakha bukwayinto ebalulekileyo echaphazela ubumanzi bekhonkrithi. Kwindawo yobushushu obuphezulu, amanzi akwikhonkrithi aphuphuma lula, nto leyo ebangela ukuba ikhonkrithi iqine ngokukhawuleza. Ukuze sisombulule le ngxaki, sinokuthatha amanyathelo okunciphisa ukushisa okuxutywayo, njengokupholisa kwangaphambili i-aggregate ngaphambi kokuxuba, okanye ukusebenzisa amanzi e-ice ukuxuba. Ngokunciphisa iqondo lokushisa, sinokucotha ngokufanelekileyo isantya sokumisa ikhonkrithi, ngaloo ndlela sigwema ukwenzeka kokumiselwa kobuxoki.
